As faculty members at Columbia University and Barnard College, we strongly condemn the Iranian government’s harsh repression of protests across the country, including the growing number of arrests within Iran’s universities. Demonstrations against the government’s imposition of mandatory hijab on women have been ongoing and widespread since Mahsa (Zhina) Amini’s death in police custody on Sept 16, the latest act of violent enforcement of its law on women’s bodies. Government security forces have met protests and demonstrations with mass arrests, as well as the excessive and even fatal use of force. We are particularly alarmed by the violent assault by security forces on Sharif University of Technology, which began on October 2nd and involved firing tear gas and live ammunition at unarmed students, along with mass detentions designed to incite fear and to break the spirit of resistance. We condemn these actions, and signal our support of our academic colleagues who are on strike in Iran, university students bravely protesting for the democratic society in which they want to live, and Iranians more generally as they resist brutal oppression and strive towards self-determination, at considerable risk to their lives.
